Feel free to increase or decrease reps, sets, and load to suit your needs on a given day.
The warmup block can and should be done as a golf prep option and as a "work in" (versus work out) on a recovery day.
You will enjoy the workout itself more if you invest 10 minutes into reviewing and watching the videos so you are mentally on board with most of the exercises ahead of time. Even a little familiarity will go a long way!
